Abstract (en)
[origin: US4339952A] An ultrasonic image of improved resolution is obtained by utilizing separate transducers for transmission and reception of ultrasonic pulses utilized for imaging, one transducer being a cylindrical or simulated cylindrical transducer having a line focus and the other transducer being aimed along the focus of the first transducer. An area to be imaged may be scanned by rotating and/or traversing the transducers as a unit.
